Treatment of laboratory mice and rats with the adrenal steroid, dehydroepiandrosterone (DHEA), produces antiobesity and broad spectrum tumor chemopreventive activity. Certain side effects are associated with DHEA administration which could limit its usefulness as a drug. DHEA can be metabolized into both testosterone and estrone and also increases liver weight and liver catalase activity. We ha...

Introduction: Rosai-Dorfman disease, also known as sinus histiocytosis with massive lymphadenopathy, is a rare benign disorder characterized histologically by lymphatic sinus dilatation due to histiocyte proliferation. Rosai-Dorfman disease accompanied by IgG4 plasma cell infiltration is an even rarer situation. To the best of our knowledge, no imaging report of fluoro-deoxyglucose positron emi...

In the title compound, C(11)H(7)F(2)N, the fluoro-benzene and the 2-fluoro-pyridine rings are oriented at a dihedral angle of 37.93 (5)°. In the crystal, only van der Waals inter-actions occur.

The fluorescent tracer Fluoro-Gold has been widely used to label neurons retrogradely. Here we show that Fluoro-Gold can also enter neurons through AMPA receptor endocytosis. We found that a 30 minute application of Fluoro-Gold to the isolated spinal cord labeled neurons under control conditions and in the presence of glutamatergic agonists including NMDA and AMPA. The labeling was abolished or...

Abstract Background Atrioventricular-nodal reentry tachycardia (AVNRT) is a common supraventricular tachycardia, particularly in younger patients. First-line therapy symptomatic patients radiofrequency catheter ablation (RFCA). Catheter placement and are typically performed by fluoroscopy guidance implying non-negligible exposure of ionizing radiation for patient laboratory personnel. Purpose W...
